Is there anyway to prevent a command from being logged in the history file?

I share a system with others (log in with same account) and I would like to prevent any passwords from being logged in the history file. Some of the commands that I run require username/password on the command line during execution.

Thanks.

export HISTSIZE=0

Passwords are NOT logged in to the history file.

That didn't seem to work.

I'm actually concerned about a password I need to supply for the command execution of a file.

ie. filename user1/password

Is yr history file not having "read" permission to you only.

If it is setup that way ... except 'root' nobody can read
that file and noway to find passwds of yr history.


Try change to 400 permissions to history file if it has not been done. yet

I think his point is that multiple people use the same login ID, and therefore can access the history of that ID. I'm not sure how to prevent writing to history.

You also have another problem on your hands -- anyone can just get your username/password from a process grep. Many programs have a way of getting around that problem, like sqlplus.

That's correct. The account is shared and my hopes are to preclude the writing of the command to the history file.

I'm aware of the process grep and can accomodate for that.

The bourne shell does not have history. So run a bourne shell, type your command, then exit the bourne shell.
